Missile flow lines are incorporated into frac manifolds, especially trailered or skidded frac manifolds. The missiles manifold the discharge from a plurality of pumps and comprise at least two junction fittings joined by spooled pipe. The junction fittings comprise a body having a primary bore and at least two feed bores. The intersections of the feed bores with the primary bore are offset axially from each other along the primary bore. The junction fittings are joined by flange unions to at least one spooled pipe such that the junction fittings and spooled pipe form a conduit including the primary bores. A discharge line from a pump may be joined to each feed union face of the junction fittings by a flange union. Thus, the discharge from the pumps may be manifolded into the conduit.

A manifold for water dispensing units includes a manifold body having: one or more inlet paths, an outlet path, a collecting chamber delimited by a lateral wall and communicating with the inlet paths and with the outlet path. The collecting chamber is configured to receive a cartridge body for the regulation of flow. A safety group is associated to the manifold body and includes: a flange removably attached to the manifold body, a safety shutter provided with through inlet gaps and with shut-off surfaces and a control body for the movement of the safety shutter: from a first position in which the through inlet gaps communicate with the inlet paths and contrast means prevent the separation of the control body and the cartridge body from the manifold body, to a second position in which the shut-off surfaces sealingly close the inlet paths. A sliding surface allows the separation of the control body and the cartridge body from the manifold body, and vice versa.

Systems and methods for accessing and monitoring a fluid within a pressurized pipe include a nozzle coupled to a section of the pressurized pipe and defining an open proximal end fluidly communicating with the pressurized pipe through an access hole formed in the pressurized pipe, an open distal end, and an interior passage extending from the open proximal end to the open distal end. A cover plate is coupled to the open distal end of the nozzle. A valve element is disposed in the interior passage and movable between an open position, in which the valve element is entirely disposed within the nozzle, and a closed position, in which a proximal section of the valve element is disposed in the pressurized pipe. A sensor port extends through a proximal end of the nozzle and positioned to fluidly communicate with the interior passage when the valve element is in the open position.

Systems and methods are disclosed for managing a cable attached to an inspection probe disposed in a pipe containing a fluid at an elevated pressure above an ambient pressure. The systems and methods include hot-tapping the pipe and attaching a launch housing to the pipe. The launch housing defines an interior chamber sized to receive the inspection probe and that fluidly communicates with the pipe, thereby placing the interior chamber at the elevated pressure. An uphole end of the cable is attached to a reel, and a cable drive mechanically engages the cable. The cable drive is operable in a forward direction, to advance the cable into the pipe, and a reverse direction, to retract the cable from the pipe.

A drilling apparatus includes a hydraulic motor 27 for rotating a drilling blade 30 that drills a pipe lining material 13, laser light sources 40, 41 for emitting laser beams toward the pipe lining material parallel to the rotary shaft of the drilling blade from positions near the drilling blade to form laser spots on the inner circumferential surface of the pipe lining material, an electric motor 28 for rotating the laser light sources coaxially with the rotary shaft of the drilling blade, and a camera 50 for photographing the trajectory of the laser spots rotating on the inner circumferential surface of the pipe lining material and a bright area that is formed on the inner circumferential surface of the pipe lining material by illumination light from the lateral pipe side. The positioning of the drilling blade is performed so that the trajectory image and the bright area image match.

An electronic device includes a body having a threaded portion configured to co-operate with a threaded portion of a duct in a sleeve in order to move the device into a final position when the device is turned. The electronic device also includes a hole punch configured to form a through orifice in a pipe while the device is being turned and to enable the device to be inserted into the final position. The electronic device further includes an electronic module configured to be in contact with a fluid passing through the pipe when the device is in the final position. In addition, the electronic device includes at least one electrical connection connected to the electronic module and passing through the body leading to a top face of the body. The body and the at least one electrical connection form a plug of the duct in the sleeve.
